| CRANK ARM CHART | |||||||||||
| CRANK SIZE | 135 | 140 | 145 | 150 | 155 | 160 | 165 | 170 | 175 | 180 | 185 |
| INSEAM LENGTH | TO 15" | 15 to 16 | 16 to 17 | 17 to 18 | 18 to 20 | 20 to 24 | 24 to 28 | 28 to 30 | 30 to 32 | 32 to 34 | 34 & up |
THE most common mistake is to buy too long of crank arms!!! Too long of arms make you swing your bike side to side, 'wag your tail' and ride a zig-zag line instead of a straight line. Too short of arms don't give you enough leg extension, therefore not enough power. BUY THE RIGHT SIZE FOR YOUR LEGS!!
